Application filed February 5, 1906. Serial No. 299,427.

To all whom t motyconcern:

Be it known that I, WILBERT C. TRUssELL, of Boston, in the county of Suifolkand State of Massachusetts, have invented certain new and useful Improvements in Hay-Loaders, of

Which. the following is a speciication.

The object of this invention is to provide a machine of simple construction which can be connected to any ordinary hay-wagon and will be eectiveA to gather'up hay from the ground and deposit it in the Wagon. Y

Of the accompanying drawings, forming a part of ,this speciiication, there is illustrated' the preferred embodiment of the invention.

Figure 1 represents in longitudinal section a hay-loader connected to a wagon. Fig. v2 represents a vertical cross-section on line 2 l2 rof Fig. 1.

The same reference characters indicate the same parts inboth figures.

The essential elements of the hay-loader consist of means, such as a rake, for gathering up. hay scattered loosely on the ground and conveying means starting adjacent the rake and extendingupwardly, having an' outlet through which the hay may be discharged into a wagon or whatever other receptacle may be provided.

The rake consists lof a bar or frame 1, pivoted at-2 adjacent the ends of an axle 3, supported upon wheels 4. From the rake-bar extend downwardly the teeth or tines 5 of the rake, which at their lower ends are inclined forwardly so as to make a small angle with the ground. The rake-bar 1 is inclined at its ends so that these portions extend.A from the pivots 2 rearwardly and convergently, while the central part 6 of the bar is offset` downwardly'or depressed, forming a space 7. The tines of the rake 'extend from equidistant oints of the bar and prevent any of the hay being passed over thereby, while the inclined. ends cause the hay as ,it is gathered to be crowded toward the center and to be crowded through the opening 7, which forms a dis-l charge passage or outlet ofthe rake. The teeth extending from the depressed portion 6 are slanted far enough forwardly to raise.

the hay and assist in causing it to pass out through the opening 7.

There is a conduit orpassage which has an inlet 8 directly behindthe opening 7, through which the contents of the rake are discharged. The conduit has side walls 9 and another Wall 10.r Adjacent the inlet end is thebottom of the conduit. Adjacent the outlet end is` the top, and in the intermediate portion is the rear wall. The conduit is attached to the rake by means of bars 11, extending forwardlyyfrom the side walls, which are connected by brackets 12 (preferably so that they can readily be detached) to the axle 3.

A conveyer is provided, which referably takes the form of an endless iiexib e belt 13, which extends from one side wall to the other of the conduit and forms the fourth and closing wall thereof. This conveyer passes over driving-pulleys 14 and guide-pulleys l5, 16, 17, and 18 and has rojections 19, which project intothe mass o hay and enable it to be positively fed along.

The conduit is made in two sections, a lower. and rear section 20 and an upper forward section 21, ofwhich the former is rigid with the -rake-axle, and the lattersection is adjustable, being pivoted to the portion 2() at 22. This pivot is concentric with the axis of the guide-pulley 16 and may be the axle itself, and thereby an adjustment of the section 21 may be altered without altering to any perceptible extent the tension of the conf veyer. Another of the guidepulleys-pulley 18-is journaled in arms23,l which project downwardly andforwardly from the pivot 22, and this pulley is close to the pulley 16. The position of the latter pulley is such as to compensate -for and neutralize .the\tendency toward variation in tension of the lbelt due to wrapping it more or less around pulley`16.

vThe adjustablesection 21 of the conduit has an outlet 24 above and forward of the rake, which is adapted to lie directly above a portion of a hay-wagon 25 to whichthe loadmg device may be attached. The outlet 24 may be raised or lowered by swinging the section 21 about its pivot 22, so as to vary the mit lengthening or shortening of the braces 26. The joint between the two sections is covered by a iiexible sheet-metal shield 29, which is connected by bolts 30 31 to the two sections. The connection of the late 29 with either section or 21 may be s otted so as to permit the necessary pivotal movement of the adjustable section. The sides of the opening are also covered by plates 32, the outer edges of which are concentric with the axis 22.

The conveyer-belt 13 is kept in constant movement while the machine 1s being moved by means of a sprocket-wheel 33, connected to one of the supporting-wheels 4, about which passes a chain 34, which also passes over a second sprocket 35, connected to the shaft 36, which supports the driving-pulley 14. Whenever the loading-machine is moved, the supporting-wheel 4 is rotated, and thereby the conveyer is driven.

The loading attachment may be connected to a Wagon by means of a yoke consisting of vshafts or bars 37, pivoted to the axle 3 and connected together at their opposite ends, being there provided with a single eye 38, passing around a pin 39, secured to the rear axle 40 of the wagon. This single pivotal connection permits the wagon to turn and the loading attachment to follow after without the shafts bein broken or the loader being moved bodily sidewise, and the outlet 24 is arranged approximately vertically above the eye 38, so that it must discharge directly above the Wagon in whatever position the loader may be with regard to the wagon. The rear art of the conduit is supported by an idle ro ler 41, journaled between the arms of a bracket 42, which is swiveled upon a stud 43, connected to the conduit.

When the loading attachment is being drawn behind a wagon, and thereby set in motion, the hay lying upon the ground is gathered by the rake and the conveyer is set 1n motion. As the hay is gathered it is massed in front of the outlet 7 and crowded therethrough by accumulating masses. This action is assisted by the projections 19, which extend somewhat into the opening 7 and catch and draw therethrough the hay. These projections carry the hay rst rearwardly through the lower part of the conduit, then upwardly and iorwardly through the intermediate portion, and finally in a generally forward direction through the adjustable section until the hay is discharged from the opening.

The device above described is simple in construction, eHicient in operation, and ada table for a variety of conditions. It is also not limited in its applicability to collecting and gathering hay, but may act also upon grain, corn, and other products having similar properties to those of hay.

l claim- 1. A hay-loader comprising a rake having a central depression forming a discharge-outlet, a conduit extending from said rake-opening upwardly and having an elevated discharge-outlet, and a conveyer arranged to move the hay into and through the conduit.
